JOHN-MARTHALER, OF JERSEY CITY, NEW JERSEY.

CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 408,731, dated August 13, 1889.

Application filed January 4, 1889i.

1' 0 all whom it may concern.-

Be it known that I, JOHN MARTHALER, of Jersey City, Hudson county, New Jersey, have invented an Improved Oar-Roof, of which the following is a specification.

This invention relates to an improved carroof so constructed that it maybe partially opened for the escape of passengers in case of accident. 7

The invention consists in the various features of improvement more fully pointed out in the claim.

In the accompanying drawings, Figure 1 is a top View of the central part of my improved car-roof with portion of the dome broken away. Fig. 2 is a vertical longitudinal central section of the same on line at w", Fig. 1. Fig. 3 is a vertical transverse section on line 3 y, Fig. 1. Fig. 4: is a bottom view of portion of the roof.

The letter a represents a car-roof provided with a large opening a, preferably at its center. This opening is surrounded by an upwardly-proj ecting flange I), having a rabbeted upper edge 1). Upon this edge there sets the rabbeted flange c of a dome or cover 0, which entirely closes opening a. Between the edges 7) c a washer cl should be interposed.

In order to lock the dome or cover 0 to its seat, I suspend therefrom the two hinged rods Serial No. 295,426. (No model.)

6. These rods project through openings a into the car, and they should be connected to the roof in such a manner that while securely locking the dome in place they may be readily unfastened in case of accident. For this purpose the lower ends.of rods 6 are bent first horizontally and then downwardly, as shown at e 6 To the lower face of roof a there is hinged a link f, slotted so as to embrace a staple g, driven into roof a. The link f may be projected over the bent portion e of rod 6, and may then be slipped over staple g, to which it is locked bya pin 71. The bent portion 6 of rod 6 coming into contact with link f will prevent any automatic disengagement of the catch.

To remove the dome c it is only necessary to withdraw pin h, when the dome may be readily lifted off the roof.

What I claim is The combination of car-roof (1, having opening a and flange 1), with. the dome c and with the hinged bars 6, having bent ends 6 c and with the hinged link f, staple g, and pin h, substantially as specified.

JOHN MARTHALER.
